iPhone developer iH8sn0w has just released Sn0wbreeze 2.6 for Windows users to fully jailbreak iOS 4.3.2 untethered running on iPhone 4, 3GS, iPad (1st-gen) and iPod touch. Just like Redsn0w, iPad 2 jailbreak on 4.3.2 is not supported yet.

Why use Sn0wbreeze over Redsn0w? If your iPhone relies on a carrierunlock, you must use Sn0wbreeze 2.6 which will help retain the old baseband for iPhone 4 and 3GS users so that they can be unlocked using Ultrasn0w. Complete step by step instructions for jailbreaking using Redsn0w on both Windows and Mac can be found here.

iOS 4.3.2 was originally jailbroken last week using PwnageToolbundles (on Mac) but it was limited to tethered boot. But now with the new version of Redsn0w and Sn0wbreeze, you can jailbreak your iPhone, iPad, and iPod touch fully untethered on the latest iOS 4.3.2 firmware.

Since building custom firmware may take some time, you can optionally play Pac-Man game to kill some time.

Step 6: Sn0wbreeze will greet you with the following “Done!” message when the custom firmware has been successfully created.

Step 7: Now follow the onscreen steps to enter DFU mode using Sn0wbreeze:

Hold Power and Home buttons for 10 seconds

Now release the Power button but continue holding the Home button for 10 more seconds

You device should now be in DFU mode

If you have followed the steps correctly, you will get the following message from Snw0breeze

Step 8: Start iTunes, click on your iOS device icon from the sidebar in iTunes. Now press and hold Left “Shift” button on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in iTunes and then release this button.

This will make iTunes prompt you to select the location for your custom firmware 4.3.2 file. Select the required custom .ipsw file that you created above, and click on “Open”.

Step 9: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs the new firmware 4.3.2 on your iOS device. Your iOS device screen at this point will be showing a progress bar indicating installation progress. After the installation is done, your iOS device will be jailbroken on iOS 4.3.2.
